baseline over time
Bald eagles removed from the endangered species list, record salmon run in the Columbia River, crab population rebound in the Gulf of Alaska; these are a few of the headlines that give people the impression that some species have recovered or the oceans and land are once again recovered. But in all these cases and many more the current population...
Soil pollution, soil contamination
Soil pollution has a major impact on the entire planet and it will play a large role in the well-being of future generations. The best we can do now is implement measures to slow down the pollution and clean up polluted areas where possible. Doing nothing will only allow the pollution to progress to a point where our soil...
Water cycle illustration
When scientists search other planets for life, the first thing they look for is evidence of water cycle steps. That’s because without water, there can be no life. Fundamental to the normal, biological functions of everything from bacteria living in deep-sea hydrothermal vents to human beings bicycling around Beijing, water is the one need all life has in common. What...
Land Pollution
Land pollution is a serious problem that impacts humans, animals, and the earth. Without taking measures now to reduce pollution levels, permanent changes to the land can occur. The adverse changes to the environment due to land pollution are subtle, but the problem is much bigger than it appears.Even though most people have a general understanding of pollution, they...
Garbage On Rocks
Water is, perhaps, the most precious resource available on the planet. For a large amount of life to exist on Earth, access to fresh water is crucial. Despite the fact that water comprises more than 70 percent of the planet’s surface, only about 2.5 percent of this water can be qualified as “fresh.” Though ample water can be found...

If you're like me, you love being right. Nothing makes me happier than listening to a friend or coworker say something wrong, then stepping up to rub your expanse of knowledge right in their uneducated face! This article is devoted to that feeling. Whether you have a true interest in the identity of misidentified animals, or you just want...

pacific sleeper shark
Information suggests that Pacific sleeper shark abundance is increasing. Pacific sleeper shark data was analyzed from fishery independent longline surveys in the Gulf of Alaska and the Bering Sea to determine the trend in abundance and whether any change was statistically significant. Relative population numbers of Pacific sleeper sharks captured in the NOAA Fisheries domestic sablefish longline surveys increased...
More than 70% of out planets surface is covered by ocean. We rely on it for many things including food, transport and pleasure. However, in recent years it has undergone many changes, most of which we have influenced. Below we explore some of the aspects of ocean change.   Understanding Change A marine biological community is the assemblage of species that co-occur...

Predation

predatory hawk flying
Predators can impact ecosystems through the process of 'top-down' control, at times resulting in changes in species composition, changes in species diversity, and regime shifts. Top predators can also help stabilize ecosystems by keeping under control the effects of more abundant smaller predators. Accordingly, understanding predators is essential to understanding how ecosystems function. The Conservation Science Institute's Ocean Initiative's...
